git-shell vs "detected dubious ownership in repository"

Hi folks,

since 2.45.1 (upgraded from 2.40.something) I cannot pull my etckeeper repositories anymore:

	# su - etckeeper
	% cd /archive/host.example.com
	% git remote -v
	origin  host.example.com:/etc (fetch)
	origin  host.example.com:/etc (push)
	% git pull
	fatal: detected dubious ownership in repository at '/etc/.git'
	To add an exception for this directory, call:
	
	        git config --global --add safe.directory /etc/.git
	fatal: Could not read from remote repository.
	
	Please make sure you have the correct access rights
	and the repository exists.

Please note there is git-shell on the remote side. Question is, what is dubious about the existing access bits of the remote repo? Currently I have

	root@host.example.com:/etc/.git# ls -al
	total 532
	drwxr-s---   8 root etckeeper   4096 May 21 10:14 .
	drwxr-xr-x 242 root root       20480 May 18 06:28 ..
	-rw-r-s---   1 root etckeeper   2716 May 17 14:04 COMMIT_EDITMSG

	-rw-r-----   1 root etckeeper 397408 May 21 10:14 index
	drwxr-s---   2 root etckeeper   4096 Jul 11  2023 info
	drwxr-s---   3 root etckeeper   4096 Jul 11  2023 logs
	drwxr-s--- 260 root etckeeper   4096 May 17 14:04 objects

Doesn't look dubious at all. Unless you are root you have to be in the etckeeper group to get read access, restricted by the top level directory and all underneath files and directories . Note the sticky bit for the etckeeper group. What is wrong with that?

Every insightful comment is highly appreciated.
